[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] like Figures 1 to 3The utility model provides a kind of double door sealing structure of vehicle refrigerator of convenient operation and excellent sealing performance is shown.The design of the sealing structure aims to solve the problem of insufficient sealing performance and inconvenient operation in existing double door vehicle refrigerator, ensure that internal temperature can be effectively maintained during use, also simplify the operation of user.

[0020] The sealing structure includes left door body 1 and right door body 2 oppositely arranged, respectively connected by hinge etc. in both sides of vehicle refrigerator door.The right end surface of left door body 1 is called first end surface 11, and the left end surface of right door body 2 is called second end surface 21.To enhance sealing effect, first end surface 11 is provided with first magnetic attraction piece 3, and second end surface 21 is provided with second magnetic attraction piece 4 at corresponding position.The second magnetic attraction piece 4 has left-right telescopic (that is, left-right movement) characteristics, and can interact with first magnetic attraction piece 3 by magnetic attraction, to realize good sealing effect.First magnetic attraction piece 3 and second magnetic attraction piece 4 are different sex magnets, or one is magnet and the other is iron piece.

[0021] To ensure that second magnetic attraction piece 4 always remains in effective contact with first magnetic attraction piece 3, elastic reset piece 5 (preferably spring) is additionally provided in the structure, which can continuously apply pressure to second magnetic attraction piece 4 in the direction of first magnetic attraction piece 3.This design not only helps to maintain sealing performance, but also enables the door body to quickly return to the closed state after closing, preventing cold air loss.

[0022] Further, the left end of second magnetic attraction piece 4 is provided with an elastic sealing piece 6, which can form an airtight structure between left door body 1 and right door body 2 when contacting the end surface of first magnetic attraction piece 3 and first end surface 11.

[0023] Sealing piece 6 is preferably a sealing rubber wheel (such as rubber wheel or silicone rubber wheel) rotatably connected to second magnetic attraction piece 4, which enables the sealing piece to effectively abut the end surface of first magnetic attraction piece 3 and first end surface 11 during movement, further enhancing the sealing effect.The sealing rubber wheel can also roll on the end surface of first magnetic attraction piece 3 and first end surface 11, reducing the resistance during opening and closing of left door body 1 and right door body 2, ensuring smooth movement of the door when opening, so as to open and close smoothly, and the opening speed and force of the two doors are uniform.

[0024] It is worth noting that left door body 1 and right door body 2 are not in order when opening, and the user can freely choose which door to open first.This design greatly improves the flexibility and convenience of use.

[0025] Furthermore, both doors open with consistent speed and force, a feature made possible by the slidable second magnetic element 4 and the elastic return element 5. Furthermore, springs are installed at the hinges between both doors and the vehicle refrigerator body, and the hinge damping and spring force are identical. This consistent opening experience also contributes to the overall stability and safety of the vehicle refrigerator.

[0026] Furthermore, a first groove 12 is designed on the first end surface 11 to securely mount the first magnetic member 3 therein. A corresponding second groove 22 is also provided on the second end surface 21 of the right door body 2, allowing the second magnetic member 4 to slide freely within the groove. A sealing sleeve can also be provided over the second magnetic member 4 to prevent air leakage between it and the second groove 22.

[0027] It is worth noting that both the first end surface 11 and the second end surface 21 are designed to be inclined from the inside to the outside and gradually tilted toward the middle. This inclined design can reduce mutual interference when the door is opened.

[0028] In addition, both inner and outer edges of the free end of the second magnetic element 4 are rounded 41. This design can reduce the sharpness of the edge, reduce wear, improve durability, and reduce the risk of injury to the user during operation.

[0029] Of course, the above sealing structure is only used to seal the joint between the left door body 1 and the right door body 2, and a highly elastic sealing strip is also installed on the edge of the door to ensure that the door can fit tightly against the car refrigerator body when closed to prevent the loss of cold air.

[0030] Through the above design, the double-door sealing structure of the car refrigerator can improve the user's operating convenience while ensuring good sealing performance, so that the car refrigerator can perform well in various usage environments.
